Two months after renal transplantation, a 26-year-old man developed pneumonia that was recalcitrant to antibiotic therapy and proved by biopsy to be due to cytomegalovirus and Aspergillus fumigatus. Ten days later while on amphotericin B therapy, he developed an endophthalmitis proved by smear and culture of a vitreous aspiration to be caused by A. fumigatus. Despite intravitreous and systemic amphotericin B the vision deteriorated and the eye was enucleated. Microscopic examination disclosed an intense endophthalmitis with vitreous and retinal abscesses. The second patient was a 29-year-old woman who developed severe hypertension and graft rejection one month after renal transplant, despite massive immunosuppressive therapy with prednisone, azathioprine, and cobalt 60 irradiation. She developed pneumonia, meningitis, and died. A postmortem examination revealed disseminated aspergillosis. A single choroidal abscess due to Aspergillus with an associated retinal hemorrhage was observed in the left eye.

25 cases of cerebral infarcts in vertebrobasilar arterial system are reported. Those were divided into 4 groups: 1. Embolism (10), the causes were NBTE, pulmonary infarct, rheumatic or congenital heart disease, coronary artery disease, respectively, and 2 unknown. 2. Thrombosis (5), the causes were arteriosclerosis, vascular malformations in the basal part of cerebrum. 3. Inflammatory infarcts (3), those were verified from tuberculosis, syphilis and aspergillosis respectively. 4. Lacunar infarcts (7), the causes were considered from hypertension. Pathologically, it was noticed that the location of embolism often situated at the terminal of basilar artery, and that if the embolism was completely obliterated, often a hemorrhagic infarction would follow. But the thrombosis in basilar artery, even the lumen was completely obliterated, any infarct would not follow, if the related collateral circulation was satisfactory. Clinically, the embolism in basilar artery often showed sudden onset, and that the symptoms of brain stem would aggravate quickly, but the thrombosis in basilar artery, if the collateral circulation was satisfactory, and symptom of brain stem might not follow.

A case of cerebral aspergillosis is reported, the presenting symptom was numbness of right face, which worsened after one year. CT-scan showed two enhanced low-density patches in the anterior and basal parts of right temporal lobe. During operation, an abscess in the deep part of right temporal lobe was revealed. The patient gradually felt amaurosis and oculomotor palsy of right eye. About six months later, she died from intracranial hypertension. Biopsy, as well as autopsy findings suggested fungal infection, and was identified as Aspergillus nidulans, which has probably never been reported in the literature.

Lung transplantation is now an accepted modality for treating end-stage lung disease. To better understand the factors limiting the survival of these patients, we reviewed the autopsy findings in 37 patients who received lung transplants. Between 1986 and 1995, 131 patients have undergone lung transplantation at our institution, including 4 patients with repeat transplantations. Of these, 48 (36.6%) died, 37 (77%) of whom had an autopsy. The autopsied patients were divided into three groups on the basis of post-transplantation interval: early (< 30 d), intermediate (31-365 d), and late (> 365 d). Of the 12 patients in the early group, 6 died of intra- and postoperative complications and 6 of bacterial infection with pneumonia in the transplanted lung. There were 18 patients in the intermediate group, of whom 11 died of infection (5 of cytomegalovirus, 5 of nonviral infections of the transplanted lung, and 1 of encephalomyelitis), 3 of post-transplantation lymphoproliferative disorder, 3 of chronic airway rejection, and one of unrelated cause. Of the seven patients in the late group, four died of chronic airway rejection, two of unrelated causes, and one of bacterial infection. Native lungs examined in 23 patients showed, in addition to the primary disease, bacterial pneumonia in 5, post-transplantation lymphoproliferative disorder in 3, cytomegalovirus in 2, and aspergillosis in 1. In this series of 37 autopsied patients, chronic rejection was the cause of death in 7 and was concomitantly seen in 3 patients (27%). In summary, the most common cause of death was infection (48%), followed by chronic rejection (19%), surgical complications (19%), post-transplantation lymphoproliferative disorder (7%), and unrelated causes (7%); rejection was not a major cause of death in the early and intermediate post-transplantation periods; in 30% of native lungs, significant pathologic findings were present in addition to the primary disease; and in the intermediate post-transplantation period, significant left ventricular hypertrophy occurred, which may be attributable to cyclosporine-induced hypertension but which needs to be further studied.

Between March and December of 1997, 3 cases of infantile cerebral aspergillosis appeared in our hospital. All patients presented some kind of immunosuppression associated with clinical findings of intracranial hypertension. After surgery, all cases were histopathologically confirmed and had positive cultures of Aspergillus. The first case was a patient with a history of subtotal resection of supratentorial ependymoma which presented a new enhancing mass on a control CT scan. Brain tumor recidiva was suspected, although, an Aspergillus granuloma was encountered on the tumor bed. Both other cases were found in patients who underwent transplantation: one presented multiple cerebral lesions after a renal transplant, and the other, after a bone marrow transplant, developed a rhinocerebral aspergillosis. The discussion was focused on the clinical findings, images and treatment of this cerebral infectious disease.

A cystic fibrosis (CF) heterozygote incidence higher than in the general population has been repeatedly reported in conditions which include clinical features found in CF, like pancreatitis, disseminated bronchiectasis, and allergic bronchopulmonary aspergillosis. Some cases may be explained by an unidentified compound heterozygosity; others could be manifesting heterozygotes. This study was aimed at detecting the incidence of CF-related clinical features in a population of carriers. A group of 261 obligate heterozygotes (mean age, 44 years) and a control group, composed of 201 individuals negative for a standard mutation panel (mean age, 36 years), were surveyed for possibly CF-related conditions (asthma, bronchiectasis, pneumothorax, allergic bronchopulmonary aspergillosis, sinusitis, nasal polyps, gallstones, liver cirrhosis, diabetes, pancreatitis, bone fractures, plus hypertension). A questionnaire was administered, and the accuracy of the statements was evaluated by phone interviews. There was no difference between heterozygotes and controls, with the exception of hypertension (carriers 28/261, controls 7/201, p = 0.004), and, in males, nasal polyps (carriers 7/126, controls 0/102, p value = 0.0178), and, again, hypertension (carriers 17/126, controls 5/102, p value = 0.0407). To avoid age bias, 126 heterozygotes matched to controls of the same gender and age were separately processed: these two groups showed no significant differences. CF-related clinical manifestations in obligate CFTR mutation heterozygotes are not more represented than in individuals with a low risk of being carriers.

A subarachnoid haemorrhage (SAH) occurred 67 days after cardiac transplantation in a 10-year-old girl with consecutive immunocompromising therapy. Neither digital subtraction angiography (DSA) nor computed tomographic angiography showed signs of intracranial vascular malformations. One month before the lethal SAH occurred, she had developed arterial hypertension and attacks of severe headache with cerebrospinal fluid (CSF) pleocytosis while CT scans showed an infarct of the left thalamus. Pathologic findings established the rare diagnosis of SAH due to aspergillosis-related mycotic arteritis. Imaging characteristics are presented.

Lung transplantation is currently the most effective means of improving survival and quality of life in patients with end-stage cystic fibrosis. In reviewing our 6-year experience we sought to evaluate complications and survival after sequential bilateral lung transplantation. Between October 1996 and October 2002, 114 patients with cystic fibrosis were referred to us from 15 Italian regional centers and 2 support centers for cystic fibrosis as possible candidates for lung transplantation. Of these 114 patients, 99 were included in the waiting list and 15 were refused. The mean time spent on the waiting list was 6.8+/-5.2 months (range 1 day-21 months) for those patients receiving lung transplantation, and 5.4+/-4.5 months (range 10 days-18 months) for those 35 patients who died while on the waiting list. A total 55 patients (6 children and 49 adults), mean age 25.6+/-6.6 years (range 9-52 years), 29 males, underwent bilateral sequential lung transplantation. One patient had a second transplantation 14 months after the first. The most frequent medical non-infective complications after transplantation were chronic renal failure (n=27 patients), diabetes (n=31), osteoporosis (n=17), arterial hypertension (n=14), seizures (n=4), transient cerebral ischaemia (n=1), and transient bilateral blindness (n=1). Bacterial lower airways respiratory infections with the organisms that colonized patients' airways before lung transplantation developed in 42 patients; cytomegalovirus (CMV) infection in 41; and opportunistic infections of the lung with Pneumocystis carinii in 3 patients. Cultures of sputum or bronchoalveolar lavage fluid grew Aspergillus fumigatus in nine patients; aspergillosis of right bronchial anastomosis developed in one patient and a lung infection in another. Another patient had a pulmonary infection secondary to Aspergillus niger. An average of 1.3 episodes of acute rejection developed per patient in the first 6 months after lung transplantation. Freedom from bronchiolitis obliterans syndrome was 95% at 1 year, 82.5% at 2 years, 70% at 3 years, and 65% at 4, 5 and 6 years. Actuarial survival rates were 80% at 1 month, 79% at 1 year, 74% at 2 years, 70% at 3 years and 58% at 4, 5 and 6 years. Ten patients (17.8%) died in the early postoperative period (1-30 days) for the following reasons: primary graft failure (n=4), multiorgan failure (n=3), Burkholderia cepacia sepsis (n=1), myocardial infarction (n=1), and pulmonary embolism (n=1). Mortality was accounted for by 9 patients (16%) who died from 9 to 43 months after lung transplantation, for the following reasons: P. carinii infection (n=2), bronchiolitis obliterans syndrome (n=4), A. fumigatus pulmonary infection (n=1), unknown cause (n=1) and suicide (n=1). In conclusion, the leading causes of morbidity after lung transplantation for cystic fibrosis are pulmonary bacterial infection and opportunistic infections. Bronchiolitis obliterans develops in more than half of lung transplant recipients who survive for more than 3 years and is an important cause of death in the late post transplantation period.

Management of transplant recipients consists in a good balance between an optimal graft function and the potential toxic effects of immunosuppressive drugs. Indeed, transplant patient monitoring has to be very meticulous and includes repetitive clinical, biological and morphological tests. Acute or chronic graft dysfunctions should be identified very soon in order to confirm diagnosis by pathologic analyses and to adapt the immunosuppressive treatment. On the other hand, the complications occurring in transplant patients have to be diagnosed promptly to start an optimal treatment without delay. The main complications are: infectious (conventional infections in the first month and opportunist infections thereafter [CMV, pneumocystosis, toxoplasmosis, aspergillosis...]); cardio-vascular because of numerous cardio-vascular risk factors occurring after transplantation: hypertension, hyperlipidemia, diabetes...; neoplasic with a major increase of lymphomas and cutaneous carcinomas incidences after transplantation. A good management of transplant recipient leads to a prompt treatment of the complications, an improvement in graft and patient' survivals and an increase in their quality of life.
